卡套接頭是裝修水路時候常用的一種材料，不過卡套式的接頭有很多種材質(zhì)?？墒菫槭裁雌x擇銅管呢？因為銅質(zhì)地柔軟可塑性強而且熔點低比較容易和其他材料之間進行融合焊接。下面小編就給大家詳細介紹下為什么卡套接頭選擇銅管？ 銅管卡套接頭,結(jié)構(gòu)簡單、密封性能可靠、使用方便、制造精良、外形輕巧美觀。不用加墊圈、不用焊接、節(jié)省材料、反復(fù)裝拆性能好。
由于不銹鋼卡套管接頭不能焊接，從而減少了管道雜質(zhì)對系統(tǒng)性能的影響。因此，不銹鋼卡套式管接頭正日益廣泛地應(yīng)用在以油、氣、為介質(zhì)的液壓氣動設(shè)備管道中，特別適用于有燃燒危險、高空作業(yè)和裝拆頻繁的場合。它目前已在我國大力推廣和使用中。這種接頭基本結(jié)構(gòu)較為簡單，只有接頭體，卡套和螺母三個基本零件組成。其中主要零件是卡套，它是一個前端帶有刃口的金屬圓環(huán)。國際標(biāo)準(zhǔn)GB3764-83對刃口推薦統(tǒng)一為I型形狀。這種接頭起主要密封作用的另件卡套，在起壓緊作用的螺母R力的軸向作用下，沿接頭體的內(nèi)錐孔軸向移動，同時刃口端在反力R'的徑向作用下產(chǎn)生徑向收縮，消除了卡套與管子的間隙，而使刃口接觸管子表面，此時管子不再旋轉(zhuǎn)，繼續(xù)旋轉(zhuǎn)螺母使卡套刃口牢牢地切入管子確保密封。另一個密封環(huán)節(jié)是卡套刃口端點13°倒角與外園的交線棱和接頭體環(huán)形錐面緊緊接觸形成密封帶，這是卡套式密封的主要部位。卡套尾86°錐面在力為F的作用下產(chǎn)生徑向收縮，緊抱被連管子，同時中部稍有拱起，因而卡套具有軸向彈性變形，這對卡套密封及防止壓緊螺母松動均起有利作用。
The card sleeve connector is a common material for fitting waterways, but there are many kinds of materials for the card sleeve joints. But why do you choose copper tube? Because copper is soft and plastic, and the melting point is low, it is easy to fuse and weld with other materials. The following Xiaobian will give you a detailed account of why the card sleeve connector selects copper tube. The copper pipe clip joint is simple in structure, reliable in sealing performance, easy to use, well made and light in appearance. No gasket, no welding, material saving and repeated loading and unloading.
Because the stainless steel card sleeve joint can not be welded, the influence of pipeline impurities on the system performance is reduced. Therefore, the stainless steel jacket type pipe joint is widely used in the hydraulic pneumatic equipment pipeline with oil, gas and medium. It is especially suitable for the occasions of burning danger, high altitude operation and frequent loading and dismantling. It has been widely popularized and used in our country. The basic structure of the joint is relatively simple, consisting of three basic parts: joint body, card sleeve and nut. The main part is the card sleeve, which is a metal ring with a cutting edge at the front end. The international standard GB3764-83 recommends the blade recommendation as a I shape. The joint plays the main sealing function of another piece, which moves along the inner cone hole of the joint body under the axial action of the R force acting on the pressed nut, while the edge ends in radial contraction under the radial action of the counterforce, eliminating the gap between the sleeve and the tube, and making the edge contact with the tube surface, at this time the pipe is no longer rotating. Turn and continue the rotary nut so that the clamping sleeve edge can be firmly inserted into the pipe to ensure sealing. Another sealing link is that the 13 degree chamfering of the edge of the jacket is closely connected with the intersection edge of the outer garden and the ring conical surface of the joint body to form a sealing belt, which is the main part of the seal type seal. The 86 degree conical cone of the caulking sleeve produces radial contraction under the action of F, and is tightly connected to the tube, while the central part is slightly arched, so the sleeve has the axial elastic deformation, which is beneficial to the sealing of the jacket and the prevention of the loosening of the nut.
